摘要
本文利用线弹性理论的二维有限元方法,计算了马17井的区域应力及井区平面与剖面的应力状态,研究该井映震灵敏的应力条件。计算结果表明井区在华北地区中强以上地震活动时具有一定的应力集中。
In the paper, the regional stress and the stress state on plane and along profile in Ma-17 well area are calculated using two-dimensional finite element technique of linear elastic theory for studing stress condition affecting sensitivity of water table in this well. The result indicates that there is a stress concentration during perparation of stronger earthquake in North China.
